I have patient care space in which cable spec is CHF cable for 517.13 redundant grounding. Is their anything like that?
Yes, but it is HCF cable. Also note that 517.31(C)(3) requires mechanical protection of the wiring of the life safety and critical branches. HCF cable does not provide mechanical protection, so its use is very limited in those branches.
